The renown which he earned by these public services was equalled by the admiration he attracted to his private life; he captivated and won over everybody by his conformity to Spartan habits. People who saw him wearing his hair close cut, bathing in cold water, eating coarse meal, and dining on black broth, doubted, or rather could not believe, that he ever had a cook in his house, or had ever seen a perfumer, or had worn a mantle of Milesian purple. For he had, as it was observed, this peculiar talent and artifice for gaining men's affections, that he could at once comply with and really embrace and enter into their habits and ways of life, and change faster than the chameleon. One colour, indeed, they say the chameleon cannot assume:
it cannot itself appear white; but Alcibiades, whether with good men or with bad, could adapt himself to his company, and equally wear the appearance of virtue or vice. At Sparta, he was devoted to athletic exercises, was frugal and reserved; in Ionia, luxurious, gay, and indolent; in Thrace, always drinking; in Thessaly, ever on horseback; and when he lived with Tisaphernes the Persian satrap, he exceeded the Persians themselves in magnificence and pomp. Not that his natural disposition changed so easily, nor that his real character was so variable, but, whether he was sensible that by pursuing his own inclinations he might give offence to those with whom he had occasion to converse, he transformed himself into any shape, and adopted any fashion, that he observed to be most agreeable to them. So that to have seen him at Lacedaemon, a man, judging by the outward appearance, would have said, "'Tis not Achilles's son, but he himself;the very man" that Lycurgus designed to form; while his real feeling and acts would have rather provoked the exclamation, "'Tis the same woman still." For while king Agis was absent, and abroad with the army, he corrupted his wife Timaea, and had a child born by her. Nor did she even deny it, but when she was brought to bed of a son, called him in public Leotychides, but, amongst her confidants and attendants, would whisper that his name was Alcibiades, to such a degree was she transported by her passion for him. He, on the other side, would say, in his vain way, he had not done this thing out of mere wantonness of insult, nor to gratify a passion, but that his race might one day be kings over the Lacedaemonians.
There were many who told Agis that this was so, but time itself gave the greatest confirmation to the story. For Agis, alarmed by an earthquake, had quitted his wife, and for ten months after was never with her; Leotychides, therefore, being born after these ten months, he would not acknowledge him for his son which was the reason that afterwards he was not admitted to the succession.
After the defeat which the Athenians received in Sicily, ambassadors were despatched to Sparta at once from Chios and Lesbos and Cyzicus, to signify their purpose of revolting from the Athenians. The Boeotians interposed in favour of the Lesbians, and Pharnabazus of the Cyzicenes, but the Lacedaemonians, at the persuasion of Alcibiades, chose to assist Chios before all others. He himself, also, went instantly to sea, procured the immediate revolt of almost all Ionia, and, co-operating with the Lacedaemonian generals, did great mischief to the Athenians. But Agis was his enemy, hating him for having dishonoured his wife, and also impatient of his glory, as almost every enterprise and every success was ascribed to Alcibiades. Others, also, of the most powerful and ambitious amongst the Spartans were possessed with jealousy of him, and at last prevailed with the magistrates in the city to send orders into Ionia that he should be killed. Alcibiades, however, had secret intelligence of this, and in apprehension of the result, while he communicated all affairs to the Lacedaemonians, yet took care not to put himself into their power. At last he retired to Tisaphernes, the King of Persia's satrap, for his security, and immediately became the first and most influential person about him. For this barbarian, not being himself sincere, but a lover of guile and wickedness, admired his address and wonderful subtlety. And, indeed, the charm of daily intercourse with him was more than any character could resist or any disposition escape. Even those who feared and envied him could not but take delight, and have a sort of kindness for him, when they saw him and were in his company. So that Tisaphernes, otherwise a cruel character, and, above all other Persians, a hater of the Greeks, was yet so won by the flatteries of Alcibiades, that he set himself even to exceed him in responding to them. The most beautiful of his parks, containing salubrious streams and meadows, where he had built pavilions, and places of retirement royally and exquisitely adorned, received by his direction the name of Alcibiades, and was always so called and so spoken of.
Thus Alcibiades, quitting the interests of the Spartans, whom he could no longer trust, because he stood in fear of Agis, endeavoured to do them ill offices, and render them odious to Tisaphernes, who by his means was hindered from assisting them vigorously, and from finally ruining the Athenians. For his advice was to furnish them but sparingly with money, and so wear them out, and consume them insensibly; when they had wasted their strength upon one another, they would both become ready to submit to the king. Tisaphernes readily pursued his counsel, and so openly expressed the liking and admiration which he had for him, that Alcibiades was looked up to by the Greeks of both parties, and the Athenians, now in their misfortunes, repented them of their severe sentence against him. And he, on the other side, began to be troubled for them, and to fear lest, if that commonwealth were utterly destroyed, he should fall into the hands of the Lacedaemonians, his enemies.
